Berberine for prevention of dementia associated with diabetes and its comorbidities: A systematic review [PDF]

, 2020
Background A growing number of epidemiological studies indicate that metabolic syndrome (MetS) and its associated features play a key role in the development of certain degenerative brain disorders, including Alzheimer’s disease and vascular dementia ...

Elucidating prognostic significance of purine metabolism in colorectal cancer through integrating data from transcriptomic, immunohistochemical, and single‐cell RNA sequencing analysis

Molecular Oncology, EarlyView.
Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

Nonequilibrium calcium dynamics optimizes the energetic efficiency of mitochondrial metabolism [PDF]

arXiv, 2023
Living organisms continuously harness energy to perform complex functions for their adaptation and survival while part of that energy is dissipated in the form of heat or chemical waste. Determining the energetic cost and the efficiency of specific cellular processes remains a largely open problem.

Inhibitory effect of Curcumin on phosphorylation NFκB-p65 induced by hydrogen peroxide in Bovine Endothelial Cells [PDF]

Journal of Advanced Biomedical Sciences, 2017
Background & Objective: NFκB is a dimeric transcription factor with multiple subunits. Phosphorylation of  p65 (one of NFκB subunits) by oxidative stress leads to the activation of NFκB.

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

Molecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

Transcriptional and translational regulation in Arc protein network of Escherichia coli's stress response [PDF]

arXiv, 2016
Recently, there has been a lot of effort in understanding sRNA mediated regulation of gene expression and how this mode of regulation differs from transcriptional regulation.In E.coli, in the presence of oxidative stress, the synthesis of sigma^s is regulated through an interesting mechanism involving both transcriptional and sRNA-mediated ...

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

Molecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Molecular dynamics simulations and in vitro analysis of the CRMP2 thiol switch [PDF]

arXiv, 2017
Collapsin response mediator protein CRMP2 (gene: DPYSL2) is crucial for neuronal development. The homotetrameric CRMP2 complex is regulated via two mechanisms, first by phosphorylation at, and second by reduction and oxidation of the Cys504 residues of two adjacent subunits.

On the existence of Hopf bifurcations in the sequential and distributive double phosphorylation cycle [PDF]

, 2019
Protein phosphorylation cycles are important mechanisms of the post translational modification of a protein and as such an integral part of intracellular signaling and control. We consider the sequential phosphorylation and dephosphorylation of a protein at two binding sites.
